Description

It is not politic to state that, in a community where most of new office spaceis air conditioned and hardly any new factory space is even cooled, this is adouble standard situation which should be intolerable in a modern society.

Where air conditioning is economically feasible, the return on investment inair conditioning from an increase in mental and physical efficiency of the workforce is assured.

The problem with the typical Australian factory is that air conditioning isnot economically feasible. Therefore, in the majority of cases, nothing isdone except mandatory ventilation, supplemented occasionally by additional fansand/or exhaust hoods over hot processes.

Factory management traditionally seeks cooling through ventilation. Thesemeasures are well intended and will relieve a situation, but ventilation alonewill not reduce temperatures below ambient conditions.

It should be remembered the effect of temperatures above 26.67C in thefactory justifies investigation on the basis of efficiency, welfare, safety andemployee relations.

Evaporative cooling, limited only by the wet bulb temperature, is economicallyfeasible and will show the same worthwhile return on investment in industryas air conditioning does in the offices.

Refrigeration provides our best cooling and evaporative cooling is clearly secondary to it.

However, it is 60% to 80% cheaper to own and operate evaporative coolers which can be used to cool hot, thinly constructed buildings where refrigerated cooling is prohibitively expensive.
